COFFEE-URN.

To all whom it may concern: I

Be it known that I, ARTH RE. WHITE, a citizen of the United States of. America, and resident of Chicago, county of Cook, State of Illinois, have invented certain new and useful Improvements in Coffee-Urns of, which the following is a specification.

' The object of my invention is a means for providing acoffee urn with a continuous supply of freshly made coffee while not interfering with the capacity of drawing coffee from. To accom ,lish this end I- have a main urn supplied wit a series of auxit at any time.

iliary reservoirs, in which fresh coffee may be made as desired.

In the accompanying drawings Figure ,1 is

a longitudinal central sectional view through a coffee urn embodying my invention. Fig. 2 is a detail view of one of the percolatorsl Referring to the parts: Themainurn con sists of'an outer vessel, A, an inner reservoir,

per edge has a flan e, 6 to rest upon the upper end of vessel, The reservoirs, b, are smaller than the reservoir of the main urn, the combined capacity of the smallerreser voirs being made preferably equal to that of the reservoir of the main urn. Reservoirs, b, have pipes, 6 leading from their bottoms through the walls of vessels, B, the ipes, b being coupled to pipes, 11 which lea into the reservoir of the main urn, a valve, I)", being laced in the ipes to regulate the flow of the iquid from t e auxiliary reservoirs into the main urn. Where pipes, I), pass through the walls of vessels, B, they are sup lied with washers and nuts to prevent the eakage of liquid in vessels, B, through the perforations in the wall. Vessels, A and B, are designed to hold water which isto be heated by gas from ipes, C,in the base, 0, upon which the vesse s A and B, rest. The cofiee from the main urn is drawn off through a pipe, a, (the faucet not being shown.) i

The upper ends of the inner vessels, a, and

b, are made to fit the ends, d, of percolators,

D. Said percolators consist of .a vessel closed at one end, d, open at the other end Specification of Letters Patent. Application filed November 20, 1905. Serial No. 288,100.

d which is held in. place by a collar, (1

The operation of this device for making .cofi'ee is similar to that shown in United States Letters Patent No. 650,129, granted May 22nd, 1900, to Charles Lewis, viz.; the ground coffee is placed in vessel, D, while it is standing upon its closed end, and while valve, W, is closed. Hot water is then poured into the vessel, D and the strainer is placed over the open end and held in place Then the percolator is placed,

bythe collar. open end downward, into one of the reservoirs. Then the valveis opened and the coffee will commence to drip through the strainer into the reservoir.

7 With myurn it is seen' that coffee may be made in one of the peroolators and be allowed to drip in to the reservoir of the main'urn, to be thence drawn off as customers call for it,

When the gage in the reservoir of the main urn indicates that the coffee is getting low in the main urn, a fresh supply of coffee may be made in another erco ator and be allowed to drip into one of the auxiliary. reservoirs, the same being then drawn off from the auxiliary reservoir into the main urn by opening the valve between the auxiliary reservoir and the main urn. A continuously fresh supply of coffee is thus being fed to the main urn without interfering with the capacity to, draw coffee off through the faucet of the main urn at" any time. The hot water in the outer vessels, A, and B, surrounding the inner vessels maintains the coffee at the proper temperature at all times.

What I claim is:

1. The combination of a main urn, a series of auxiliary reservoirs whose bottoms are in a plane above the plane of the bottom of the main urn, pipes leading from points near the bottoms-of the auxiliary reservoirs into the- *main urn and a series of percolators from which coffee may be percolated into the main urn and into the auxiliary reservoirs successively.

2. In a coffee urn the combination of a base, a main urn, auxiliary reservoirs supbottom in a plane below the bottoms of the inner vessels of the auxiliary reservoirs, pipes leading from points near the bottoms of the inner vessels of the auxiliary reservoirs to the inner vessel of the main urn and percolators from which coffee may be percolated into the main urn and into the auxiliary reservoirs. v

3. In an apparatus for the infusion of beverages the combination of a main reservoir and an auxiliary reservoir both having open tops and the bottom of the main reservoir extending below the bottom of the auxiliary reservoir, a pipe leading from the bottom of the auxiliary reservoir into the main reservoir and percolators consisting of vessels open at one end, closed at the other, with valves in the closed ends and strainers over the open ends of the vessels and with seats formed at the open end of the vessels to fit upon the upper ends of the main and of-the auxiliary reservoirs.
